Splitting Cone
Cone splitter is an attachment that turns your world’s most effective stump crusher into the world’s most effective cone splitter in just within 15 minutes.
As there are 4 parallel crests in our splitting cone with a massive 30 mm (1,2 “) thread pitch. This means that each revolve goes as deep as 150 mm/5,9” into the tree trunk.
The tip of the cone splitter is made from Toolox 44. It is a pre-hard-ened steel for extrusion dies and engineering components, produced by SSAB. Its hardness (HBW) is 410-475 which is the same as wear resistant steel Hardox 450.
The tip is also replaceable.
Stump Removal That Doesn’t Create Extra Work
On most sites, stump removal is only “done” when the ground is ready for the next step. The SC600 removes stumps efficiently while keeping disturbance tighter—so you spend less time fixing holes, levelling, and cleaning up.
Reliability
Consistent performance and uptime ensure efficient, reliable service with minimal interruptions and quick response times.
Performance
Speed and efficiency ensure tasks are completed quickly and resources are used optimally, enhancing productivity and satisfaction.
Scalability
Growth capability is a system's ability to scale and adapt, meeting increasing demands and evolving needs for long-term success.
Where the 850 Pro pays for itself
On major corridor and infrastructure jobs, stump removal can decide the timeline. In large-scale work, teams have reported finishing a 100-hectare scope in roughly 50 days versus about 70 days with traditional approaches – often reaching up to 2 hectares per day depending on site conditions and stump density.
Traditional uprooting can also stack costs quickly: hauling and landfill fees. With the 850 Pro, stumps can be processed directly on site, cutting out a lot of time to “move it, store it, handle it again” part of the job.
If you’re clearing big areas on a deadline, speed is good. Fewer extra steps is better.
Built for development sites and utility corridors
The 850 Pro is for the jobs where you’re not doing “a few stumps.” You’re doing hundreds – sometimes thousands. It’s built to run on 13-30 ton carriers and keep a consistent pace so the rest of the operation doesn’t wait on stump removal.
Simpler logistics on large sites
Digging stumps out creates a chain of extra work: holes to fix, root balls to move, stockpiles to manage, and often soil/stones mixed into the wood. Processing stumps in place helps reduce hauling, reduces stockpiling, and keeps the workflow cleaner across the site.
Serviceable by real crews
Wear parts are designed to be replaced, not babied. Blades are boltable and dual-sided, and the center screw is replaceable. It’s built for crews who want predictable maintenance – without turning a simple job into a workshop project.
Built for Big Stumps and Long Days
The 850 Pro is the attachment you use when time per stump matters. High torque, stable performance, and a setup that’s meant for repeat work – railways, highways, power lines, forestry, and large-scale site clearing. It’s not built to look clever. It’s built to finish the area.
Technical Specifications
Power & Hydraulics
Designed for 74-130 kW excavators with working pressure 180-350 bar. Make sure your carrier can provide the required hydraulic flow under load – not just on paper.
Cutting Capacity
850 mm cutting diameter with 900 mm drilling depth gives you the reach for large stumps and deeper removal where the next phase needs clean ground.
Gearbox & Torque
High torque is what keeps removal consistent when stumps vary all day. The 850 Pro is built for repeat work in tough root systems without constant “nursing” by the operator.
Everything You Need to Know
What excavator size do i need for the 850 Pro?
The 850 Pro is built for 13–30 ton excavators. If you’re below that range, you’ll usually be underpowered or under-flow, which reduces output and can stress the carrier.
What hydraulic flow does it require?
Target range is 110–230 l/min. Flow matters because it affects cycle speed under load. If your carrier’s flow drops significantly under load, real productivity drops with it.
What working pressure does it need?
180–350 bar. Pressure supports torque under resistance. Your setup should be able to hold working pressure consistently during operation.
My excavator is in the right ton class, but power is lower. Will it still work?
Sometimes, but output will be lower. If your work is occasional or stumps are smaller, it may still be fine. If it’s daily production work, matching power properly saves you money in the long run.
Does it fit quick couplers?
It depends on your coupler type and dimensions. We can supply mounting solutions, but we need your coupler standard and excavator model to confirm.
Can I run it on a long-reach excavator?
Yes, as long as the hydraulic requirements are met and the carrier is stable for the operating position. Long reach can reduce stability and precision if you’re working extended.
Can it be used on backhoe loaders or other carriers?
The 850 Pro is primarily meant for excavators in the specified class. If you have a special carrier setup, share the machine specs and we’ll tell you straight if it makes sense.
How deep can I remove the stump?
Up to 900 mm drilling depth. Actual required depth depends on your next phase (grading, planting, foundations, access).
What stump sizes is it meant for?
Large stumps in production environments. The point of the 850 Pro is not “can it do it,” but “can it do it all day without slowing the site down.”
How many stumps per day can I expect?
It depends on stump diameter, species, soil, density, and operator rhythm. If you share typical stump sizes and site conditions, we can estimate realistic throughput.
Can it handle dense root systems and hardwood?
Yes. That’s exactly where torque and stable operation matter. Species and root structure affect time per stump, but the machine is built for that variation.
Does it work in rocky soil?
Rocky sites are possible, but like any cutting tool, stones increase wear. The key is operator control and realistic expectations for consumable life.
Wet ground does it make the job harder?
It can work, but access and ground stability become the limiting factor. One advantage of processing in place is you typically avoid creating the massive holes you get from uprooting.
Can it be used in winter / frozen conditions?
Yes, within reason. Frozen ground changes resistance and can affect performance. If you operate in deep frost, we recommend discussing typical winter conditions so expectations are realistic.
Does it throw debris like a traditional grinder?
It’s generally more controlled than aggressive side-to-side grinding. That said, any stump processing creates chips—jobsite safety and PPE still apply.
Why is it better for infrastructure corridors (rail/road/power lines)?
Because scale punishes extra steps. If you dig stumps out, you create hauling, holes to fix, and stockpiles. Processing in place reduces that chain and helps the next phase start sooner.
Can I chip and reuse material on site?
Often yes, depending on project requirements. Processing in place typically keeps the material more usable than uprooted stumps mixed with soil and stones.
Does it reduce landfill and transport costs?
In many projects, yes—because you’re not hauling root balls to disposal. Exact savings depend on local disposal rules and site plan.
Does it help projects start earthworks sooner?
Typically, yes. When stumps are processed in place, you can move faster into topsoil stripping, grading, and embankment work versus waiting on extraction and cleanup.
Is the end material cleaner than uprooted stump chips?
Often, yes. Uprooted stumps tend to carry soil and stones. Cleaner material is easier to handle and more likely to be reusable.
What are the main wear parts?
Boltable dual-sided blades and the replaceable center screw are the key consumables. They’re designed to be swapped without turning the job into a rebuild.
How often do blades need replacing?
Depends on stump species, soil, stone content, and operator technique. We can give a realistic range if you tell us the typical job conditions.
Can I flip the blades instead of replacing them?
Yes. The blades are dual-sided, so you can rotate/flip to extend life.
How hard is routine maintenance?
Routine checks are straightforward. The idea is predictable upkeep—service it like a working attachment, not like a delicate tool.
Does it require special tools for service?
Normal workshop tools cover most needs. If there are specific service requirements, we provide guidance and documentation.
What about gearbox maintenance?
Follow the service schedule and oil requirements. Gearbox health is mainly about correct setup, proper operation, and staying on the maintenance plan.
Do you supply spare parts and consumables?
Yes. We recommend keeping a basic consumables set on hand if you’re running production work.
What PPE is recommended?
Standard jobsite PPE applies: eye/face protection, hearing protection, safety boots, and appropriate workwear. Keep safe distances like you would with any cutting operation.
Can it be used near buildings or sensitive areas?
The 850 Pro is mainly for large-scale work, but it still operates with controlled processing. For tight urban areas, the smaller models may be the better fit.
Can it damage underground utilities?
Any below-ground work carries that risk. Utility locating and site checks are your responsibility. If utilities are present, plan depth and approach accordingly.
Does it require special operator training?
If you can operate an excavator properly, you can operate the attachment. We provide guidance on technique, safety, and maintenance to get consistent results quickly.
What’s the lead time?
Lead time depends on production schedule and region. Request a quote and we’ll give you a clear timeline.
Do you ship internationally?
Yes. Shipping method and cost depend on destination.
What warranty do you provide?
Warranty terms depend on region and purchase channel (direct/dealer). We’ll provide the warranty terms in writing with your quote.
What support do I get after purchase?
Parts availability, documentation, and technical support. If you’re running production work, we recommend setting up a parts and service plan up front.
Can you help me choose between 600 and 850 Pro?
Yes—and you should ask. Tell us your carrier model, stump sizes, stump density, and typical job type. We’ll recommend the model that makes sense instead of upselling.
